digitalmars.D.learn - sokol-d: Static Struct
- Matheus Catarino (30/30) Dec 30 2023 Hi everyone. 👋
- ryuukk_ (5/5) Dec 30 2023 Use https://renderdoc.org/ and check and compare frames for both
- Matheus Catarino (5/10) Jan 03 I debugged some existing bindings, and despite any user-level
- ryuukk_ (117/127) Jan 03 I managed to compile your project, ``sgl_context`` is working for
- Matheus Catarino (7/14) Jan 03 Wow! Cube and blend work, too?
- Renato (7/11) Dec 30 2023 Sorry if I sidetrack the discussion, but I was amazed by the Zig
- Matheus Catarino (21/30) Dec 30 2023 I don't doubt it. I'm experiencing D in just a week. (Newbie)😅
- Matheus Catarino (6/18) Feb 02 Finally fixed!! Works in, linux/macos/windows/wasm32(need emsdk)
Hi everyone. 👋 Currently I'm working on D binding for sokol project (truly a dual bindgen [sokol-tools, sokol-header]) which could be merged into the upstream project. Up to now, my "ideal" configuration has been to run all the ported examples (from other supported bindings) on Drt or betterC provided safe has DIP1000 enabled (not obligatory). Except for the "clear" example (no have structs) works, the rest of the examples have partial execution, without 2D/3D animations, like the original ported examples. e.g.: https://github.com/kassane/sokol-d/blob/main/src/examples/sgl_context.d Based on the articles in the official documentation, I tried to use `__gshared` (no ` safe`) to attribute both the display and offscreen structures inside state, but it didn't work. ```d disable struct State { disable this(); disable this(this); __gshared Display display; __gshared Offscreen offscreen; } static assert(!__traits(isDisabled, State)); static assert(!__traits(isCopyable, State)); ```

Use https://renderdoc.org/ and check and compare frames for both your working and non-working example That'll give you an idea at what could be wrong I suspect you have a typo in one of your definition I'll try to take a look later

Cube and blend work, too? And on my machine it doesn't rotate, just like I initially posted.I had to remove this from your build script tho: ``try cmds.append(b.fmt("--mcpu={s}", .{lib.target.getCpuModel().name}));`` [...]Please! This deserves opening an issue about it. Because Zig is normally set native build by default. What version of LDC is used? 1.35?

That sounds very interesting.

That sounds very interesting.Hi Renato, I'm glad you liked it. This is an experiment, as I haven't adapted to the dub yet. Zig's goal at this point is to share `libsokol` configurations and replicate in the D compiler (currently, ldc2 only). If you want to see the result, just run `zig build clear --verbose`. ``` <Zig build> -> build(exe) -> build libsokol -> (optional) zigcc-wrapper -> build D example (using libsokol config) -> switch (cc/linker system or zigcc) -> binary (exe/lib) ``` I added some comments to `build.zig` explaining each point. If you have any questions, you can ask in the repo. I saw that you are a MacOS user, I suggest you see issue/1 [closed] focused on zigcc wrapper. **TODO:** It is intended to add dub support and will continue with Zig build-system support, including zig-pkg(v0.12.0/master - git url) for downloading and integrating C and D packages.

Works in, linux/macos/windows/wasm32(need emsdk) I was having trouble with the floating/double init (nan) and solved this issue by giving default values to structs fields.
